That's why I said the introverted vs. extroverted were the main differences between the two ^^; I still feel personality wise they're both fairly similar, just their execution that makes them so different.
Really? I don't remember it being that bad. I know when she was doing her "carefree" act she started flirting with everyone, but it never seemed like toying or intentionally hurting them. Harry was the one who was toying with girls and not caring about hurting them in the end.
Em Jay at first the beginning didn't bother me because it being a different universe, I'm fine with them taking whatever direction they want. And I liked that by issue 9, when she figured out that Gwen is Spider-Woman, is the moment when she stopped acting really selfish and really grew as a character, and by the Mary Janes special issue, she became really good and I was really enjoying her. Also she may be the first real bi/gay MJ, so that's a plusAlso I'm not a big fan of Em Jay. However she's getting better and I'm also going to be honest...she is alot like 616 MJ during her beginning earlier days written. I'm a fan of many characters but many times the bad or lackluster is faded out/glossed over while holding onto just the good. Early days MJ outside of her iconic character intro shot there wasn't alot at the time going for her with me. She loved to party and be center of attention and be catty (plus I know they reckoned that she was secretly helping Peter knowing his secret by wanting to go to the Rhino attack but considering when that was written she didn't 616 early MJ isn't using common sense to the point she didn't that agian and Spider-man/Peter had to scold her for it after saving her).
From that I can see Em Jay and 616 MJ being variants. That during their youth they cared only about themselves and having the attention. 616 MJ has had 50+ years of character developments to move past that phase while Em Jay has now 4 years and yet slowly moving at a decent pace of development. Looking over the issue numbers to when each of the positives stand outs happen for 616 MJ and putting that in perspective in years today (12 issues per year unless a series has a double issue per month like current Spider-man) if we start listing them down we might see a HUGE time gaps. With the level of patience general public and fans have for characters nowadays a big advantage for 616 MJ currently has over others is a Wiki page where a person can absorb tons of stand out info written by a fan (I usually find issues MJ appeared but did nothing or just plays up her party girl attitude isn't covered that much because it's doesn't make a impact or importance to the 616 MJ of now for people to know or we want to let people know usually). 50+ years compiled on one wiki page to be disgusted. Em Jay isn't high on my favorites (mid range currently but was much lower) but if she has the time and the writers continue her own path of developments and possibly stand outs scenes in the positive then she too can rise to a higher level (my top favorite MJs are the one who balance mature and fun and shows cares for others vs the self).
